hi,
go through the attached file, and calculate the list of resonant frequency which is like this
Mode No. Frequency(Rad/sec) Frequency(Hertz) Period(Seconds)
1 21203 3374.6 0.00029633
2 21343 3396.8 0.00029439
3 22798 3628.4 0.0002756
4 26778 4261.8 0.00023464
5 28895 4598.8 0.00021745
Suppose the same assembly if shaft is made to run at 1000 RPM is the structure safe and stable.
In case if i am not able to predict this in frequency analysis, should i go for dynamic analysis in which (modal time history, harmonic, random vibration) which one to select and what are the inputs required to start any of these dynamic analysis. Please go through the attached file
